Cannot get rid of #.{jsessionid} in urls

Question

So far I have tried two approaches:
-1. Add to web.xml:

<session-config>
    <tracking-mode>COOKIE</tracking-mode>
</session-config>

-2. Using pretty faces, add to pretty-config.xml:

<rewrite match="(?i)^(.*)#\.\w+(.*)" substitute="$1$2" redirect="301"/>

-3. Jetty specific. Add to web.xml:

<context-param>
    <param-name>org.eclipse.jetty.servlet.SessionIdPathParameterName</param-name>
    <param-value>none</param-value>
</context-param>

Nothing helps. Also I cannot understand, what the difference between "#.{jsessionid}" and "jsessionid={jsessionid}" formats (where {jsessionid} is some hash-looking string )?

edit1:
It looks like fragment-id. What is he doing on all my URLs?

Answer 1

This hash is not jsessionid. It is appended by addthis tracking. To disable it use:

<script type="text/javascript">
var addthis_config = {
"data_track_addressbar" : false
};
</script>

I don't know, may be it is better to delete the question, as it's kind of stupid.
